How do you seperate the two? When we talk about Fritz or Rebel, we are talking
about them running on some kind of minimum system. Fritz5 isn't going to run on
a 286. Perhaps I am talking about something different (which was the point of my
previous post) than some others here are. And not only am I having some
arguments with the terminology, but with some concepts as well. When you talk
about 'the strongest' program, are you talking about best in computer-computer?
That's very likely different from computer-human or problem set testing. I think
we need to be more specific in our definitions. And I don't think this is a
pedantic request either. Some people are very interested in computer-computer
testing, others (like me) are much more interested in results against humans.
And against humans, I'm interested in both platform equal performance, and it
overall performance. If Crafty on a quad is the best in the world at speed, then
I'll spend some time watching it on ICC simply because it is the best,
regardless of it's performance on a single processor.

Perhaps not typical, but still valid. But what I'm really asking is the above
question. If we are going to ask 'What is the strongest program on a single
processor system, as measured by computer-computer testing?', then that gives us
some important and useful information. But different information from the
question I stated in the last paragraph. Asking for 'the strongest' program is
like asking about 'the fastest' car. There are many caveats, and if they aren't
taken into account in the formulation of the question, then the question becomes
virtually meaningless.

>What was the account of the guy with the overclocked Xeon?

I don't remember the account name. He was chatting in the computer channel. He
said he was going to start running Crafty on it on ICC. Perhaps someone else
remembers his name, but if he really is getting 2 million NPS with Crafty, I
think we'll all be hearing about him shortly. Don't know why someone would
overclock an $8,000 machine like that (from 450 to over 600), but it should be a
killer before it fries itself.
